Ian Maund f1b32d4e47 Merge upstream linux-stable v3.10.28 into msm-3.10 
The following commits have been reverted from this merge, as they are
known to introduce new bugs and are currently incompatible with our
audio implementation. Investigation of these commits is ongoing, and
they are expected to be brought in at a later time:

86e6de7 ALSA: compress: fix drain calls blocking other compress functions (v6)
16442d4 ALSA: compress: fix drain calls blocking other compress functions

This merge commit also includes a change in block, necessary for
compilation. Upstream has modified elevator_init_fn to prevent race
conditions, requring updates to row_init_queue and test_init_queue.
